The 8051 microcontroller does not have a specific "compare jump equal" instruction. Instead, conditional jumps can be achieved using a combination of the CJNE (Compare and Jump if Not Equal) instruction, which checks two registers and jumps if they are not equal, or by using the JZ (Jump if Zero) instruction after a subtraction operation. By setting up the comparison manually and then checking the result, you can effectively implement a compare-and-jump-equal functionality.

Is the following a valid instruction cjne a p2 over?
The instruction "cjne a, p2 over" is not a valid instruction in standard assembly language syntax. Typically, "cjne" is an abbreviation for "compare and jump if not equal," and it usually requires two operands for comparison and a label for the jump. The correct syntax would involve specifying two registers or immediate values to compare, followed by a label to jump to if the condition is met. Therefore, this instruction is incorrectly formatted.
Is jne An instruction for the assembly language?
Yes. JNE is the Jump Not Equal instruction and all assembly languages support it.
What are the different conditional jump instructions of 8051?
The 8051 microcontroller features several conditional jump instructions that allow the program to branch based on specific conditions. Key instructions include JC (Jump if Carry), JNC (Jump if No Carry), JZ (Jump if Zero), JNZ (Jump if Not Zero), JP (Jump if Positive), and JM (Jump if Minus). These instructions enable the microcontroller to make decisions and control the flow of the program based on the status of the flags in the accumulator or the special function registers.
What is jump instruction?
That could be trampoline, or skydiving...
What is pseudo instructions?
A pseudo-instruction doesn't actually exist in the instruction set of a processor. A pseudo-instruction will be a convenient single name for one or more actual instructions. A common example is the unconditional jump instruction. Normally the syntax for this instruction would be: jmp address ...but the assembler might actually translate that into: cmp t0 r0 r0 jmp t0 address Which is basically checking to see if the zero register is equal to the zero register, and if so jump. Since this will always be true, it will always jump.
How many bus cycles are required for an unconditional or a conditional jump instruction in 8086 microprocessor to be executed?
when conditional jump instruction is executed it has 10 m/c cycles bt when nt executed it has 7 m/c cycles....while unconditional jump instruction has 10 m/c cycles...
How many bytes are there for jump instruction in 8085?
There are 74 instructions in the 8085 microprocessor.
What jmp instruction assembles if distance is 0020h bytes?
If the distance for a JMP instruction is 0020h bytes, it typically assembles to a short jump instruction (if the target is within a certain range) or a near jump instruction. In this case, a near jump would be used, which consists of the opcode followed by a 16-bit offset. The exact opcode will depend on the assembly language and architecture, but for x86, a near JMP could be represented as EB for a short jump or E9 followed by the relative address for a long jump.
On Lion King the game how do you jump?
Read the Instruction Booklet.
In super Mario galaxy how do you kick jump?
as far as i know, it is not possible to kick jump. check the instruction manual, it has all of mario's moves in there. as far as i know, it is not possible to kick jump. check the instruction manual, it has all of mario's moves in there.
What is jump on carry in 8085?
Jump on Carry is simply a "JUMP" instruction which will transfer the control to some specific location if carry flag is set. For Example: JC 2004H This instruction will take the control to address location 2004H if carry flag is set.
Why is the jump instruction jmp of 8085 microprocessor given the immediate addressing mode?
because the operand is available in the instruction itself
